Recently, genome-wide linkage studies have identified genomic imbalances involving IMMP2L gene in 7q31.1 that are associated with autistim spectrum disorders (AUTS9) (MIM 611015) [2], attention deficit/hyperactivity disorder (ADHD) (MIM 143465) [3] and Gilles de la Tourette syndrome (GTS) (MIM 137580) [4]–[7]. The gene discussed is IMMP2L; the disease is attention deficit-hyperactivity disorder.
